That is actually not true. One thing is always better than another. For example, the Xbox one line-up is far superior to me. The problem here is that we once again run into a subjective discussion. Which as we all know is something that seems too complex for forums to handle.
This is where we need to separate what is better as a fact, vs what is better as an opinion, and I'm referring to what makes something better as a fact.
For example, we know $100 is better than $1 as a fact. $1 being better because I like the design of the dollar bill better is simply better by opinion.
Another example, we know a high end gaming pc is better than a console as fact in regards to what's under the hood. Preferring to play a console because I find console better is an opinion.
And mind you, I'm not targeting this at any one particular person or side, it goes both ways. One console isn't better because it has more AAA games or indies than the other as fact, but rather, it just makes it better to that individual based on their preference. That's fine, and I agree with that. But here, in these forums, way too often, people try to put down what others prefer, and use the "this is why ours is better, so there" statement, and then use because of **insert sales, more games, AAA, indies,etc** excuse.
I don't know, but me personally, and obviously I'm in the minority here, I find it a strange argument....claiming one console is better due to more AAA, without even discussing those games themselves.
